Application led August 12, 1.909. fserial No. 512,574. To all whom itmay concer/ii.' provide means to facilitate the correction'of Be itknown that 1, ALBERT SWI'NDLER, a citizen of the United States, residingat Browns Valley, inthe county of Montgomery have invented certain newand useful Improvements in Writing- Machines -for the Use of the Blind,of which t-he following is a specification. A

There are at the present time three recognized and well known systems ofproducing raised characters for conveying information to the blind. TheYork ,point is errors in the product of the machinefa to i produce suchimprovements in details of constructionasshall be hereinafter `point-edI out.

knurled head 42V by means of which the slia ft may be rotated. Theopposite end ot' shaft 41v is provided with a knurled head 43 which issplined upon shaft 41 by means of a pin 44 carried bythe shaft andprojected into keyways 45 (Fig. 19). Head 43 is priolvidedwith tworatchet wheels 46 and 47 which may be conveniently formed integral butwhich have different numbers of teethso thatthe amount of rotationproduced upon roller 40 by means f the spacing lever 48 may be varied tocorrespond with the system of embossing which is being produced by themachine.

' Inorder to readily adjust head 43 so as to bring one or the other ofthe ratchet wheels 4'6 and 47 into alinement with the spacing lever 48,I form a circumferential groove 49 in head 43 and mount therein a smallsprin which is projected into the interior head 43 -so thatit may bebrought into either one of two circumferential grooves 52 `formed inshaft 41, (as clearly shown in Figs. 19 and 20,) and thus hold ,the head43 'and the ratchet wheels 464 and 47 carried thereby, against axialmovement. The s acing lever 48 is pro vided at one end with a fihgerpiece 53, by means of which .it ma be easil operated, and at theopposite en is provi ed with a spring dog 54 adapted to engage the teethof either ratchet 46 or 47. Carriage 33 is normally urged in onedirection by means of a usual spring drum 55 connected with the carriageby means of a tape 56, and in order to hold the carriage against theaction of the drum 55, I inount upon the carriage, the spacing bar 57which is provided with a plurality of uniformly s aced notches 59adapted to coperate with the spacing dogs to be described.

, In order that the carriage may be automatically released for movementin either direction when the paper is spaced forwardly, bar 57 iscarried by a pair of brackets 59 which are pivoted at 61 to the end barsof the carriage 33, 4and each oi" these brackets is provided with a slot62 arranged to receive the pin 63 carried by a cam 64 mounted upon ashaft 65, which is normally urged in one direction by means of a spring66, the spring serving to normally retain bar 57 in the position. shownin Fig. 5.

may be rotated from either end so as torelease the carriage,-I secure,to that .end opposite spacing lever 48, a -lever 67 provided with a pin68 lying within groove 62 of the adjacent bracket- 59.

Frame 30, at a point beneaththe travel oftlie-paper 37, after it hasissued from the feed roll 38, is provided with a guide block 71, whichis provided with a plurality of perforations in which are mounted aplu-v rality ot punches 73, 74, 75 and 76 arranged in a series parallelwith the line of movement of the carriage; also a series of plungers 77,78,79 and 80,also arranged in a series parallel with the line ofmovement of the carriage and in alinement, transversely of the line ofmovement of the carriage, with the series 73'to 76; also two lungers 81and 82 arranged in a line parailel with the line of movement of thecarriage, with plunger 81 in transverse alineinent with plungers 74 and78 and lunger 82 in transverse alinement with p ungers 75 and 79.Plungers 73 and 76 at their lower ends are spread away from the plungers74'and 75 in the line of movement of the carriage, as indicated in Fig.6. llungers 77 and 80 are spread at their lower ends to oints beyondplungers 73 and 7 6 respectively and plungers 78 and 79 are s read attheir lower ends to points between ut out of alinement ioo respectively.Plungers 77 and 8O are spread at their lower ends to oints beyondpluiigers 73 and 76 respective y, and plungers-81 and 82 are spread attheir lower ends so as to come into transverse alir'iement with plungers77 and 80 respectively, and .the lower ends of the' various pluiigersare reduced toforin shoulders 83 (Fig. 5a) and the reduced endsprojected downwardly through 'suitable openings formed in a plate 84.

Pivoted upon a pivot pin 85 are key levers 86, 87, 88, 89, 90, 91, 92,93 and 94, the outer end of each of which is provided -with a suitableinger piece by means of which it may be readily operated. The fingerpiece ends of the several levers are suitabl)y spread so as to affordsufficient room for operation but at.tlieir inner ends the severallevers are brought into parallelism and closely com- 'llie inner end ofkey 87 lies beneath the lower ends of plungers 77 and 81,

key 88 beneath plunger 73, key 89 beneath plunger 78, key 90 beneathplunger 74, key 91 beneath plunger 75, key 92 beneath plunger 79, key 93beneath plunger 76 and key 9e beneath plungers 80 and 82.- It will beseen from the abovethat plunger-s 74., 7 5, 78

' and 79 may be used either 4in the New York point, Braille or Moonsystems but that, for the New York point system piangere I81 and. 82cannot be used, while plate 103 and movable in the line of move' lne-ntof the paper carriage, is a dog carrier 1, 111 upon which is mounted aswinging dog l 112 which may be brought into vertical 1 alinement withdog 104 by the action of the 1 paper carriage, or may be shifted to thep05 they are 'used for the Braille, and that. t sitionsh'oivnin Fig. 12,oran intermediate plungers 73, 76, 77 and 80 cannot be used forpoint,'by means ot' a light spring 113 (see the Braille system.

In order, therefore, not `to require an unnecessary number of tin-ger:keys in order to adapt @bhe machine for use with either Aof -thesystems, I make the plate 81 movable longitmdimaily of the inner I endsof the keys (transversely of the line of movement of the paper carriage)so thatl by shifting said plate the lower ends of the vpl-ungers may be'shifted relatively to the keys. The inner ends of keys 88 and 93 arethen made somewhat shorter than 'the inner ends ofthe keys 89, 90, 91and 92, (see Figs. 6 and 6*) so that, when the plaie 84C is shifted tothe position' shown in 68, vthe lower ends of plungers 73 and 76 will becarried out beyond the endsof the keys 88 and 93 respectively, so *thatsaid keys will become inoperative so far astheir plungers are concerned.

For like reason the inner end of key 94 is provided with aplunger-engaging toe 95 (Fig. 5) of such limited extent that it can-'not possibly engage more than one of the plungers-SO and 82 which arein alinementwith the innerend of the key 94, so that, when the plate84is in the position shown in Fig. l6, pluri er 80 will be in position tobe actuated and w ien the plate is in-the positon shown in Fig. 6,plunger 82 will be in position to' be actuated., by key Similarly key 87is provided with a toe-JG which is arranged to have either plunger' 7 7or Aplunger 81 brought into position to be engaged thereby.

Plate 84 may be shifted into either o f its positions by a half rotationof cam 9'7'Which is provided wit-ha suitable operating handle 98.

Arranged on bar 135 l(to be described later) is a guide 101, and a.sliding bar 100 which carr/ies a guide 102. Projected into guides'101and 102 are guiding fingers of a verticallyT i'eci'procable dog plate103 which carries a fixed dog 104 adapted to coperate with the space bar58 and to be moved into and out of the notches thereof by a verticalmovement which carries the dbg into and out of the plane of the. catchbar. The dog plate 103 is extended at its lower end into 'a guideway 30andat an intermediate point an operating lever100.the rear end of whichis connectedat 107 with a yoke 108, pivoted upon pin 85 and extendedbeneath all ot the levers 87-to 94 inclusive. Dogplate 103 is normallyurged upwardly by means of a spring 109.

' is provided with a notch 105, inwhich rests' Slidably mounted upon dogdotted lines Fig. 11). The dog carrier 111 is i guided by'its engagementwith the dog plate l, 103 and is also provided with a guiding tail 1141projected through an extension 115 on a plate 103 (see Fig. 17).

In any of systems the space occupied by any' Eart-icularlletter willdepend upon 4the ngum erof horizontal points used in its production and,in order that there may be ance with the number of horizontal pointsused' 1.n any let-ter, the movement of dog 112 relative to dog 1011 mustbe` gaged in a-cmay have been used i-n the reduction of the letter. vFor this purpose vprovide the following mechnism. The dogearrier 111Vis', by the force of drum 55 and the action of paper carriage A33thereon, normally held -in engagement with a shoulder 116, (see E ig.13) and said dog carrier is provided with a series of spacer blocks 118,119, 120. and,

the distance between two notches 58 in the spacer4 Vbar 57. The first ofthese spacer blocks 118 lies a distance fronrthe normal position ofprojection 11 7'; substantially equal to the distance bet-Ween twonotches 5 8 of the spacer bar 57, so that when the dog plate 103ls-drawn downward-ly and dog"112 is thereby withdrawn from enagementwith the teeth 4of spacer bar 57 and og 104 isthrownintoienvagement with saidteeth, dog carrier 111 will be shifted, by itsspring '113, the discoming into engagement-withspa-cer block 118 andbeingstopped thereby so that., .when the dog plate 193 rises, dog 112will enter a projection 117 below which are arranged 121, the` thicknessof which corresponds to.

a movement of the paper carriage 1n accordf Y y `cortilance with theparticular plungers whichA tance vof one ,space 58, the projection 117'a notch 58 next succeeding that`into 'which .dog 101 has beenproyect'ed, thus permitting the paper carriage to advance oneste so'soon as dog 104 has been withdrawn. Similarly. by withdrawing thespacerblccks 118 to 121 inclusive, some or all of them, the amount ofmovement of the dog carrier 111 may-be varied so as to'permit the paperearriage'to advance fronrone to 4five steps at a single movement, thusproviding for the production of a character occupying from one to fourhorizontal points and automatically providing for a uniform spacebetween the character irrespective of the number ot' horizontal pointf.occupied thereby. l

In order that the withdrawal of the spacer blocks 118 to 121 inclusivemay be entirely automatic I provide a plurality of controller bars 123,124, 125 and 126, each of which is normally held by o ne of' a series ofsprings 127. The keys 87 -to 94 inclusive are each provided withoverhanging fingers 87 to 94 inclusive respectively andthe cont-rollerbar 123 is provided with ,four fingers 123 which are projected beneaththe overhanging fingers-87', 88, 89 and 90. Similar controller bar 124is provided with a plurality of fingers 124 which are projected beneaththe fingers 91, 92', 93 and 94. lController bar 125 is provided with twofingers' the spacer block 121, bar 125 to'spacer block 120, ar 124 tospacer block 119, and bar 123 to spacer block 118 (Figs. 5, 6 and 16).

For producing characters of the Braille system with a uniform space foreach letter, it is necessary to produce a uniform movement of thecarriage irrespectiveof the keys which may be operated and for thisreason I provide bar 124 with a finger 124 which may be engaged by aprojection 131 on a key 131 which may be locked down by throwing itunder a shoulder 132 (Fig. 2)

' thus drawing down the two spacer blocks 118 and 119 and keeping themdown throughout the entire operation of the machine, so that anyoperation of the dog plate 103 will permit a three space movement of dogcarrier 111 and dog 112 carried thereby. 4

The entire s acing mechanism is carried upon bar 135 pivoted at13(dotted'lines Fig. 10) on anaxis parallel witlrthe line ot' move ine'nt of the paper carriage and provided with depending arms 137` at itsends and middle to support the controller bars. This pivotal mounting ofthe spacing mechanism is advisable in order that the fingers of the.'controller bars 124, 1,25, and 126 may he drawn back from under theprojections 87' to 94 inclusive, when the machine is to be used forroducting Braille system which requires ut two points horizontally inthe production ofl any'letter. For thev purpose of producing thiswithdrawal I provide a..

latch 138 connected at one end with one of the depending arms 137 andprojected outwardly from the front ofA the casing 30.

Lateh-138 is provided with two notches139 and 141 (dotted lines Fi 10)which serves to hold the latch in eit er one of its two positionsandsaid latch is urged downwardly by a light spring 132.

To produce characters according to the Moon system it becomes necessaryto control the movement of the carnage s o as to spring 148l but may belocked down by that there be no autotrol the'plungers 74, 75, 78, 79, 81and 82. vFor that reason bar 100 needs to be shifted to the right (Fig.13) to the positionshown in Fig. 15 so that projection 117 is broughtlclosely adjacent spacer block 118' thereby preventing any movement ofdog 112 in the line of movement 'of ,the upper carriage.

until block 118 has been' withdrawn. For the purpose of producing thismovement of har 100 and holding the same in its shifted position, Iprovide said bar with a transverse cam slot 145 (Fig. 9) through whichis projected a slide 146 provided -wlth anelilarged end 147. Slide 146is connected to a key 86 which is normally held up'bybea ing carriedunder a shoulder 149 (Fig 2). When the parts are in this .position of ajustment, it is necessary to prevent'movement of dog carrier 1 11 untilthe projection 117 has been brought below the top of spacer block 118and for this p provide a pawl 151, the free end of ich is brought to thevertical plane ofthe initial face of block 118, as clearly shown in Fig.16, said pawl yielding upwardly whenever projection 117 has been carriedbeneathit and' is on its return movement to normahg's the. papercarriage advances.

uvrpose. 'I

ln order to produce a spacing between words I pivot upon pin 85 a.pair'0farms 152 which lend out beyond the keys and are connected hy abar 153, vthe-levers 152 projecting 'ahove yoke 108 so as to operateagainst it in exactly the same'way as theV The spacing key and thevarious keys.

other keys 87 to 94 inclusive are'each norv mally held in their upperposition by suit. able springs 154, and the several plungers 73 to S2inclusive are normally urged downwardly so as to be retracted from theupper face of guide block 7l, by means of light springs 155.

Arranged above guide block 71 is an anvil or die 156 which may beadjusted toward and from the face of block 71, and hence toward and fromthe upper face of' the paper 37, by means of suitable adjusting screws157. The block 156 is provided on its anvil face with suitable pocketsor` def pressions 158 int'o which the paper may be pushed by theplungers. It often occurs that' the operator will have failed to producea, proper Acharacter and I .have therefore provided means by which acorrection can be readily made, The o erator having discovered an error,will p ace a finger of one hand, upon the point of error and tlin withthe other hand will bring to posi ion a pointer 161. the tree end otwhich verlies the line ot characters which has jusbeen produced, so thatthe pointer thereoflwill lie opposite the erroneous character. {Themarker 161 is slidingly mounted upon thle shaft 65 ot' the -papercarriage and is heldin any desired position by means of "may, the pointsof the erroneous character, using a pawl:163, the free end of which maybe swung into any one of the notches 58. It the only corect-ion desiredis the addition ot one or iiioic points tothe chaiacter the operatorthen has merely to move the carriage backwa'd until awl163 engages guide102 at wliic point t ie erroneous character will have beten brought toproper positionto lie immediately upon the characterforming plungers,whereupon the additional points may .be' added to the character. If,however, too many points have been produced in the erroneous character,the operator with a blunt' instrument press down the pointer 1 61 as agage, and return the paper toll position to receive a roper iinpression,whereupon the pointer is returned Ito its normal position at the extremeleft hand end Hof the carriage.

If the operator desires to produce characters in the New York pointsystem lie will lirst lswing lever 98 to the position shown in Fig. 6,thus making available plungers 73 to 80 inclusive, i. e. two horizontalrows of four* points each, thus inaking fourvertical rows of'two pointseach and all of the keys 8.7 to 94 inclusive will be used in suchcombination as may be desired to produceI tlie proper characters,projectingl the plungers upwardly into the paper in a well known manner.Atthe same time latch 138 will be mo 'ed to the position shown in Fig; 5where adi of the ngers of the controller bars arein position to beengaged by the overliangi'ng portions of the respective keys. 4

lVith the parts in these positions a depression of either of keys 87 and88 will swing the controlling bar 123 and thus cause the withdrawal ofthe spacer block 118 and permit a forward movement of the paper carriageof two spaces one to compensate for the character formediby one or bothot the plungers 73 and 77 a d one tol provide for the space between thcharacter and the next succeeding character. A depressionl of either ofkeys 89 or 90 will actuate controller bar 124 which, because itsllingers overlie the fingers of controller bar 123, will cause awithdrawal of spacer blocks 118 and 119, thus permitting a three spacemovement o the paper carriage. An actuation of either of keys 91 or 92will act upon controller bar 125 and consequently upon controller.

bar 126 and thus upon all of thel preceding controller bars, therebyretracting all ot the spacing blocks 118 to 121 inclusive and permittinga tive space movement` of the paper cai-ria e. With this adjustment,plungers 81 'an 82 are in position where they cannot be actuated by anyof the keys.

In'order to produce-characters in accordance with the Ideal Braillesystem the operator will pull latch 138 to the position' sliownin Fig.10, thus withdrawingl the tingers of controller bars 125 and 126 frombeneath the projections of their respective keys and leaving only the'fingers o bar's 123 and 124 in position. The operator will also swinghandle 98 to' the position shown in Fig. 6?, thus throwing plungers 81and 82 into commission and plungers 73, 7 6,

controller 77 and 80 out of commission in the manner already described.The pa e'r feed will be correspondingly adjusted. Vith this system theoperator will use only keys 87, 89, 90, 91, 92 and 94 and the firstthree of these keys will operate only upon controller bar 123 and thuswithdraw o'nly spacer block 118 and causeA a two step advancement of thepaper carriage, while the remaining three keys will operate uponcontroller bar 124 and thusvserve to withdraw spacer blocks 118 and 119and cause a three stepadvancement of the paper-carriage. Tol reducecharacters according to the Regu ar Braille system, the operator willdepress key 131 and' lock it in its depressed position, thus producing auniform three space advancement of the aper carriage for each actuationof any c aracter keys or space keys. i 'Io produce characters accordingto the Moon script system, the operator will permit key 131 to return.to 'its upper position and will` depress key 86, thus preventing anyspacingaction as a -resul't of the depression ot' the space key 153,(dueto pawl 151 as already described) and thus prevent any movement ofthe carria e. This results in a holding of the carriage in positionafter the production of any vertical line or lines of characters so1that a character of anydei 88 or 93 may be used asspace keys. l
